It was on this day in 1904 that Theodor Seuss Geisel was born and the creation of Dr. Seuss had been put in motion.

Geisel wrote 48 books under his seudonym Dr. Seuss and many more were written under his formal name.

Geisel's books are still incredibly popular with young children and in 2015 a follow-up release of "What Pet Should I Get" became a best-seller.

One of his most famous children's books, The Cat in the Hat, was published in 1957.

On September 3rd a new Dr. Seuss book will be released based on a manuscript by the late children's author. It will be titled "Dr. Seuss's Horse Museum" and will feature artwork by Pablo Picasso and Jackson Pollock.
